• How do I stop apps trying to use a dial-up connection?

  - by ProfKaos

  Every now and again, I might have to use a dial-up internet connection via another tethered phone, i.e. Bluetooth connection to the GPRS modem. Now I am back on 'ops normal', i.e. using a shared internet connection on my own phone, or on my 3G stick, but some apps, especially IE9, keep popping up a 'dialup connection' dialogue, which I cannot dismiss enough times ever, to make to stay away. How can I tell these idiot applications that I no longer need a dial-up connection?

• Turn old rack server into a telephone server

  - by Jake Elsley

  I have an old server lying around and I am thinking of using it as an internal telephone server. Its main use would be to set up a 1 to 1 telephone system that could be used internally to connect to different users in different offices. I have looked at software like Asterisk, but it seems that this is mainly for external telephone systems. Is this possible to do with Asterisk (or other software) or is this not possible without involving a VOIP company?

• internet disconnects

  - by Smokezzaj

  Internet disconnects and reconnects, computer is in a peer to peer workstation with two other computers XP o/s. Only one computer has this problem the other two don't disconnect. Computer's connect to switch no router is being used. Ipconfig shows a DHCP connection, local area connection status shows packets being sent out but packets are not being received or being received at a extremely slow rate. Tried Winstock tool, reinstalling network card driver, restored to previous date, checked ethernet cable and release/renew IP.

• Using an audio cable (or similar) to create unidirectional communication from a secure server

  - by makerofthings7

  I'm interested in exploring how a semi-offline Root CA can be used to update CRLs to the sub CA's. This answer on Security.SE mentions using an audio cable for this purpose. Doe anyone have details on how an Audio cable (or similar) can be used to create a unidirectional path of communication? Since I'm a .Net programmer, I'm also open to code samples, drivers, etc that may enable this scenario.

• Most secure way of connecting an intranet to an external server

  - by Eitan

  I have an internal server that hosts an asp.net intranet application. I want to keep it completely and utterly secure and private however we need to expose some information through a WCF service to another server which hosts our external websites which CAN be accessed by the public. What is the best way to pass information between the two servers with regards to an IT setup, while keeping the intranet in house server completely secure and inaccessible? I've heard VPN was the way to go but I wanted to be sure this was the safest way. Another question what would be the most secure way of passing data in the WCF service?

• Using Static Public IPs and Private DHCP IPs on the Same Router

  - by Andrew Larsson

  I have a subnet of public IP addresses that my ISP has provided me with. They are routed through my router (how profound) that has a a static IP. I have successfully assigned the IPs from that subnet to various devices on my network. This works just fine, they get their own public IP, they can access the Internet, and the Internet can access them. However, I would like to also assign some private IPs on my network through that same router and put them behind NAT. Is this even possible? Could a VLAN be of use? I would like to avoid putting another router on the network, which makes this is quite an awkward question.

• Get details / solve issue with a kernel panic?

  - by Joseph

  I have a Lenovo T430 running Linux Mint 13 (MATE): joseph:~$ uname -a Linux joseph-T430-LM 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I installed Mint immediately after getting the laptop about two weeks ago, and have noticed that about once a day, the computer will completely freeze up- I can't use Ctrl+Alt+Backspace to restart X, I can't use Ctrl+Alt+F1 to get a text only terminal, can't move mouse, can't type, and if any music was playing it just gets stuck in about a 1-second loop. There is a Windows partition, but I haven't had any issues in Windows. I couldn't find a common thread between the freezes, they were seemingly random (sometimes right after I clicked the mouse, sometimes not; sometimes with Pandora/flash being used, sometimes not, etc). I assume they're kernel panics since it completely locks up, but the laptop doesn't have a capslock or scroll lock LED. It is on a dock and I do have a USB keyboard, but the scroll lock/capslock lights do not flash when it happens (not sure if this is indicating its not a kernel panic, or if the kernel panic just wouldn't illuminate the LEDs on a usb keyboard attached to a laptop dock). This was annoying but not terrible. However, I've found a way to reproduce it. I have a particular CSV file that when I open up in LibreOffice Calc and scroll around, the same thing happens- complete lock up. I really need to use this file, so I'd like to fix the issue, but at the least it's given me a test case to work with. So, having a case where I can cause this issue, what can I do to better find out what's going on? I've looked in /var/log/syslog but haven't found anything seemingly useful. Any thoughts?

• How do I see what connections are being made?

  - by Coldblackice

  My DDWRT router is showing that my computer has a connection count around 600! The router is at 100% CPU use. How can I see what's making all the connections? So far, I've opened up Resource Monitor and checked the network tab. I can sort by which program is using the most network bandwidth (Pale Moon browser), but I can't see what's making all of the connections. Or rather, where all the connections are being toward (trying to find what tab must be making all of these connections). I've also tried netstat -A, but it apparently doesn't show the actual number of connections being made. At least, the list of established connections isn't very long, by any means (like enough to account for the 500+ connections apparently being made.

• How to access internet from 2 laptops with data card plugged-in in one of the machine?

  - by learnerforever

  Hi, I have 2 laptops - one running Windows XP and other running Vista. Both have wifi card.I have one Reliance broadband data card. I want to be able to access internet on both the machines simultaneously using this one data card. Please help. I think, there would be many many ways to do it. I do have some linksys router but any simple quick way without any extra hardware? like we could set up p2p or WLAN between these 2 machines, because both have wifi card so we shouldn't compulsorily need any extra hardware(?) I am fine with connecting data card to either of the machines. Thanks,

• No communication on my VLAN?

  - by Donovan

  I am using a Netgear FSM7328S switch and have designated ports 19-24 as being part of VLAN # 3. I designated them all as untagged because I do not want them to switch traffic to any other port on the switch. I also removed them from the default, untagged, VLAN 1. My issue is that none of the ports 19-24 will communicate with eachother. My laptop plugged in with wireshark shows no switched traffic what so ever. Have I configured it wrong? Thanks, D

• Connecting to Aerohive APs from Laptops running Win. 7 using authentication from a Windows 2008 domain server

  - by user264116

  I have deployed a wireless network using Aerohive access points. 2 of them are set up as radius servers. I want my users to be able to use the same user name and password they use when they log onto our domain. They are able to do this from android devices or computers running Windows 8. It will not work on Windows 7 machines. How do I remedy this situation, keeping in mind that the machines are personal machines not company owned and I will have no way to change their hardware or software.

• Bonjour/DNS Service Discovery queries

  - by senloe

  I'm trying to implement dns service discovery in my application (no, I'm not asking for a programmatic answer). What I believe is one of my big pain points is generating the query. I know I need to send out a multicast broadcast on port 5353 and want to look for devices of type _ipp._tcp and _print._tcp, but I don't know what the question section needs to look like. For example, in SSDP I sent out a query that looks like the following: "M-SEARCH * HTTP/1.1\r\n" "HOST: 239.255.255.250:1900\r\n" + "MAN: \"ssdp:discover\"\r\n" "ST: urn:schemas-upnp-org:device:Printer:1\r\n" "MX: 5000\r\n\r\n" From what I know about a DNS query I need to send something like: "_ipp.tcp,all,all" but I know there needs to be more. Any pointers to documentation, etc would be greatly appreciated! update rfc1035 appears to contain promising information re the message structure.

• Nokia 5800 v50, getting "Invalid server name" with ad-hoc wlan with Windows 7

  - by Krunal

  After upgrading to v50 firmware in my Nokia 5800 xpress music phone. I am not able to connect to ad-hoc wlan network in my laptop(Windows 7 OS). I have a dialup internet connection and created wireless ad-hoc network to access the internet in my phone. But I am getting "invalid server name" in the phone and my wireless network access type in Windows 7 shows "no internet access". I am able to connect to wlan infrastructure network using 5800 in my office. So my phone is working with wlan and I m able to access internet on it. BUT The problem is "dial up with ICS enabled" and "AD-HOC wlan network" in Windows 7. Can anyone give some solution on it. Or can you provide a guide/tutorial to connect 5800 with adhoc network and dialup internet in Windows 7. System: Windows 7 Dial up internet connection with ICS enabled. Ad-Hoc wireless network with WEP Nokia 5800 Xpress Music phone Note: I have read other posts also and tried their solutions but didn't worked for me. the first solution is to bridge the network and access it. but how can I bridge the dialup and wlan netwok? second solution is manually configure IP and DNS addresses in phone. But what should I add as IP and DNS as my dial up and adhoc network have automatic addresses.

• Linksys SRW248g4p and hp procurves

  - by Garfield81

  We've got about 3 procurves linked up with about 5 linksys srw248g4p. Pinging between the Procurves I get ping time between 1-2 ms and pinging between the linksys the ping time are averaging 40 ms. I have evening tried pinging between two linksys switches that are connected to each other directly using the GB ports. There have no modification done to the switches and the firmware seems to be uptodate. Any suggestions would be appreciated.

• Assigning static IP and domain name mapping to local server in LAN

  - by yashbinani

  I have developed a web application which will be deployed in a LAN environemnt. Clients will be Computers/Android Tablets/IPAD In order for communication between client and local server 1) need to assign a static IP to local server. 2) need a domian name mapping for that IP address in Local environment. 3) router should assign the same static IP if it gets restarted etc. I am using a windows XP machine as Local server OS. Do i need to take care of router configurations before buying one, or all routers will have same capability to perform this task. I am not a network specialist, so Sorry if this question sounds stupid. Thanks

• How to bridge multiple wireless access points (and internet entry points) into one network

  - by amccormack

  I have two DSL lines coming in to wireless access points and then running to a RV082 Gateway/Bridge. The gateway then runs to a switch, which runs to multiple PCs and a Printer (See picture below). Normally, I would set up the wireless access points behind the gateway, but they are also the modems for the dsl. I have found that I can not print to the network printer if I am connected to the wireless network, but only if I am connected to the wired network. How can I configure the Gateway and APs (Routers) so that the PCs and Printer are all on the same internal network? I have tried turning DHCP off or redirect on the APs and redirect them to the Gateway. However, neither of these worked. Furthermore, I tried pinging the Gateway from the AP but got no response.

• How much network latency is "typical" for east - west coast USA?

  - by Jeff Atwood

  At the moment we're trying to decide whether to move our datacenter from the west coast to the east coast. However, I am seeing some disturbing latency numbers from my west coast location to the east coast. Here's a sample result, retrieving a small .png logo file in Google Chrome and using the dev tools to see how long the request takes: West coast to east coast: 215 ms latency, 46 ms transfer time, 261 ms total West coast to west coast: 114 ms latency, 41 ms transfer time, 155 ms total It makes sense that Corvallis, OR is geographically closer to my location in Berkeley, CA so I expect the connection to be a bit faster.. but I'm seeing an increase in latency of +100ms when I perform the same test to the NYC server. That seems .. excessive to me. Particularly since the time spent transferring the actual data only increased 10%, yet the latency increased 100%! That feels... wrong... to me. I found a few links here that were helpful (through Google no less!) ... Does routing distance affect performance significantly? How does geography affect network latency? Latency in Internet connections from Europe to USA ... but nothing authoritative. So, is this normal? It doesn't feel normal. What is the "typical" latency I should expect when moving network packets from the east coast <--> west coast of the USA?

• Joining two routers together, but I have no access to the second router, although I know it's IP address and Gateway

  - by JohnnyVegas

  I have temporarily moved into a rented apartment for 4 months, which has wireless. The trouble I am having is that the access points here are wifi only and no RJ45 and I need to use RJ45 to connect some equipment that I am working with. I have purchased an RT-N66U and installed Tomato (shibby ver. 1.28) and successfully replaced the existing access point, but now I want to enable the access point that I have replaced as it links wirelessly to 3 others. Can I plug in a cable from the access point to my RT-N66U and get it to access the internet via my router? I have no access to the existing wireless access point, and don't want to reset it as it's not mine. There is another router situated in the roof somewhere which I also have no access to, but it's supplying my RT-N66U internet and I most definitely have a double-nat, which although isn't the best way of doing things I am limited with what I can do. Any suggestions on routing tables, vlans etc would be helpful, but I have no experience in these fields before - but I know the tomato firmware can cater for this. My router is set to IP 10.0.1.1 and dhcp is 10.0.1.100-200 The wireless access point address was 192.168.1.2 but this was assigned by the router in the roof which has the address 192.168.1.1. There is a cable from this router going to a wall socket which I now have my RT-N66u attached to via the WAN port. I understand it's scruffy and it isn't the way to do things but I have tried to ask for the admin details but as the wireless network is looked after by a third party and nobody knows their details I am stuck with this dilemma. I could buy three wireless access points and replace the existing but this isn't what I want to do, and although I have installed plenty of DD-WRT wireless repeater bridges they simply don't work here for some unknown reason. The phone line here is very noisy too and I don't have the rights to install ADSL in a building that isn't mine, and 3G coverage isn't good enough either. Thanks for your time

• Route packets from one VPN to another

  - by Mike

  I have two OpenVPN servers (10.8.0.0 and 10.9.0.0) set up on my OpenSUSE server. Within one network, each computer is visible to any other one, but I'd like to make it so that computers are visible across networks. I'd like to route the packets like this: when a user (say 10.8.0.6) pings an address on the other VPN (10.9.0.6), the packets are routed to the 10.9.0.1 and then to the appropriate computer in this VPN. How do I achieve this using iptables or a different tool? I tried the commands at the end of this section with no avail.

• Ping only works after about 30 seconds

  - by Ricardo Polo

  Today I am working on this issue and I would love your ideas. There is a network with something like this LAN 1 -- WAN CHANNEL--- LAN 2 The LAN 1 have two segments. When I make a ping from LAN 1 segment 1 it works like a charm. When I make a ping from LAN 1 segment 2 I have no ping, but after about 30 seconds of continues ping (ping -t) it start to work perfect. After some time of no activity with the destination host the issue happens again. Tracing the route packets stops in the last router before the target. This is the first router in LAN 2 after the WAN channel. In the next screenshot you can see thie issue, the first ping is before a continuos ping and the second one is while continous ping is running. Thank you in advance

• Need help creating advanced context menu command in Windows 7 (x64)

  - by Craig

  I found out about ForceBindIP and I really love it, so much that I am using it regularly enough to where spamming the same command prompt over and over again is getting painful. Here's ForceBindIP and what it does: http://www.r1ch.net/stuff/forcebindip/ I'm on a 64-bit of Windows 7 Home Premium. What I want to do is add a right-click context menu item so that when I browse items in Windows Explorer, or on my desktop, I can automate a ForceBindIP command (through the prompt). I am permanently connected to two networks: one over ethernet, and one over wireless. My ethernet network takes priority. What I want to do is add a "Run through wireless network" context menu item, that will send the item through this command: ForceBindIP {5F657824-9E3B-46E5-C21E-F52585R6457E} "[path to right-clicked file here]" It will need to run that command in C:\Windows\SysWOW64. I've no experience at all playing with the Windows registry or writing batch files, anything of that sort. I was wondering if anyone here would be kind enough to assist me?

• How to connect the virtual networks of vmware guests running on different hosts?

  - by gyrolf

  In a test setup, we are running several virtual machines on a single vmware workstation host. All virtual machines are connected via a "host only" network. This runs fine up to 2 or 3 virtual machines (depending on the host hardware). To allow more virtual machines, we want to use more host machines. Details about the environment and applications: Host PCs are running Windows XP in a corporate intranet. VMware used is Workstation 6.5 Guests are running Windows Server 2003 All guests act as Web Servers One of the guests additionally acts as Windows File server, offering shared folders for the other guests to connect to. Restrictions: VMware guests shall not be visible from the intranet. Changes to the host PC are restricted by corporate policy. In the virtual network, no domain controller exists. All virtual machines are member of the same workgroup. Running the virtual network as NAT is possible. Port forwarding might be used if it does not conflict with ports used by the host PC. Looking for a solution, I found hints about using router or vpn software on the hosts, but without any details how to setup. (I found a similar question Sharing the network between 2 VMware hosts, but the answer was not sufficient for me.)
